CAN-OPENER.

SPECIFICATION forming part of Letters Patent-No. 790,006, dated Mey 16, 1905.

Application led September 30, 1904.v Serial No. 226,671. f

To all, w/mml it may aon/cern:

.Beit known that we, ABRAHAM M. Sourir- Ann and @mannen L. SOUTIIAnmcitizens of` the United States, residingat Denver, Denver county, Colorado, have invented a certain new and useful Improvement in Can-Openers, of which the followingis a full, clear, and exact description, such as will emtblelothers skilled in the art to which it a'ppertains to make and use the saine, reference being had to the accompanying drawings, forming part of this specilication, in-whicli- Figure 1 is a perspective view`of a can, showing our invention applied. Fig. :2 isa vertical longitudinal sectional view through the invention at the greatest d-epth of the ott-- set. Fig. Bisa vertical longitudinal sectional view through the invention at the shallowest Fig. 4 is a sectional view on the line l 1 of Fig. 3, and Fig. 5 is a view illustrating in detached detail the cuttingblade.

This invention relates to can-openers, one

i f ofthe objects thereof being toprovidca canby the cutting edge of the blade will not accidentalbv puncture the can-top.

Other objects and advantages, as well as the .novel details of'constr-uction, of this inven'- tion will be specifically described hereinafter,

it being understood that changes i'n the form,

proportion, and minor details of construction maybe resorted to without departing from the spirit or sacriticing any of the advantages thereof.

The preferred form of the can-opener is illustrated in the accompanying drawings, in whichl 1 indicates aveovc'radapted to be placed over a can of the proper size, winch can is designated by the numeral 2, the cover being'l provided with a flange 3 for this purpose. The flange v3 is formed with an outwardlyprojecting bead 8, which is of approximately thosame height as the depth of the offset 4,

which forms a recess or pocket for the reception of the spring-blade The pocket formed by the oil'set is illustrated asbeing segmental in foriu-that is. it extends from the point designated as r( to the point designated as L- said pocket gradualb1 increasing in depth from the point a to' the point 1;, so as to house the' spring-blade 5 on the under side of the cover. be pressed into shape, and on account of its peculiar construction-J. e., ,being of gradu. lally-increasing.; depths-fthe spring-blade 5 y will be in a position to contact with the 'wall of said pocket at any intermediate adjustment between the points 1l and If. Another advantage is that in moving the blade 5 down to the stop 1l the blade will be automatically forced into proper cutting position and it will not be l necessary to shriner it out of a -recess 75` against the face of the cover. As soon as the .blade is moved away from the stop 1'1'it will begin to recede into the deeper portion of the recess, so as .not to be operative against the top of the can upon which the covcrisplaced. One end of the cutting-blade is illustrated as being bentand provided with a sharpened' edge. as at 6. The opposite end is provided with a circular opening,l 7. is provided in the cover,vwhich registers with the opening 7 ,in the blade, which opening in the cover is centrally located and receives a, rivet 9, which passes through both the opening in the cover and the opening in the blade to secure the blade to the cover.l

11 designates a projection which is formed in the top thereof, and ,this projection 11 provides a stop for the blade 5, against which the The pocket formed b v the offset may A similar opening p blade rests when in its operative position. 'In

actual practice it is intended to construct this blade of spring metal, and the inherent yielding tendency thereof will cause it to spring f xo into the deepest portion of the recess formed by the offset-ft` asvtlieblade is moved away from-the stoptLgl l yWhen it is'dcsired to open the'can, the cover 1 may be removedyfrom the can Q and the blade 5 mayl be moved on its .pivot until The cover mayit rests against the stop 11. thenbe vreplaced upon the top of the can. and by pressing upon ,the cover at a point imme diately above the cutting-blade and at the same time rotating the cover the cutting edge or point (i will pierce the top of the can, asindicated'at 10 in Fig. 3, so that the rotation of the cover will cause an arcuate slit. to be cutl in the can-top'or a complete revolution ofl the cover willl cause the entire top to be cut v By providing the bead 8 on the cover 1 of the same height as the oii'set 4 the cans may be' readily packed one upon the other for vtransportation without the liability 0f having their tops accidentally punctured by the points 6. y u

B v reference to Figs. 2 and 3 it will be observed that the rivet is provided with fiat heads, so that the opening in the cover through which .thel rivet projects practically forms a seal to exclude the outside atniosiihcre when' the cover isin place, thereby preserving the contents of the can. i n

Having thus described-the invention, what is claimed as new, and desired to be secured by Letters Patent, is- 1. A loose, rotatable cover for cans having an offsetprovided with an inclined wall forming a recess increasing in depth from the plane of thetop of the cover,- and a cutter movable along the inclined surface of said recess from -an inoperative to an operative position; sub'- stantially as described. 'v

2. A can-opener comprisinga loosely-rotavtable4 cover having an oti'set of gradually-im .I

creasing depth, a swinging cutter carriedV within the recess, and4 means 4for limiting the swinging movement of the cutter; substantially asdescribed.

3. A can opener comprising a rotatable cover having an offset of graduallyancreasng depth, a cutting-blade` a rivet for securing' the cutting-blade to the cover and within the as described.

4. A can-opener comprising a rotatable cover having'a periphe1all,\ 'arranged ange offset, land means for limiting the swinging movement of the cutting-blade; substantially with an outstanding bead., an offset in the,y

cover of gradually-increasing depth, the deepest portion of the otfset'being not in excess' of the depth of the bead, a cutter' within the recess formed by said offset and having a swinging movement; scribed.

su bstantially vas i de- 5. A can-opener comprising a rotatable cover having a peripherally-arranged ange cover of grad cally-increasing depth. the deepest portion of the oset being .not in excess ot' the depth of the bead, a cutter wlnin the recess formed by said oii'set and Aaving a swinging movement., 'and a depressie: in the top of the cover comprising a stop for limiting the swinging movement of the cutter; sub- 65 v with an outstanding bead, an oii'set in the l.
